SpeechRecognitionResult: isFinal property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The isFinal
read-only property of the
SpeechRecognitionResult
interface is a boolean value that states
whether this result is final (true
) or not (false
) — if so,
then this is the final time this result will be returned; if not, then this result is an
interim result, and may be updated later on.
Value
A boolean value.
Examples
js
recognition.onresult = (event) => {
// The SpeechRecognitionEvent results property returns a SpeechRecognitionResultList object
// The SpeechRecognitionResultList object contains SpeechRecognitionResult objects.
// It has a getter so it can be accessed like an array
// The first [0] returns the SpeechRecognitionResult at position 0.
// Each SpeechRecognitionResult object contains SpeechRecognitionAlternative objects
// that contain individual results.
// These also have getters so they can be accessed like arrays.
// The second [0] returns the SpeechRecognitionAlternative at position 0.
// We then return the transcript property of the SpeechRecognitionAlternative object
const color = event.results[0][0].transcript;
diagnostic.textContent = `Result received: ${color}.`;
bg.style.backgroundColor = color;
console.log(event.results[0].isFinal);
};
